OF ST. LOUIS, MISSOURI.

SPECIFICATION forming part of Letters Patent No.'286,25'7, dated October 9, 1883.

Application filed July 31,1852.

To a who/22 it may concern Be it known that I, FREDERICK B. BROWN- ELL, of the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Hanging and Operating the Doors of" StrcctGars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention consists in the described means of moving the rear door of a car from the front platform; also, to th e described means for hanging the door, combined with the operating appliance.

In the drawings, Figure 1 is aside view of of a car with part of the side broken out to to end of the car. Fig. 2 is a horizontal section at 2 2, Fig. 4. Fig. 3 is a detail front view of the treadle-lever by which the main lever is operated. Fig. I is a rear view of the ear with part of the wall broken away, showing the door and part of the operating apparatus in rear elevation. Fig. 5 is a view similar to Fig. 4, except that the operating and supporting devices are somewhat modified. Fig. 6 is a diagram showing a n'lodifieation.

A. A are the side walls, B the rear wall, and (I the front wall, of a car. D is the platform. E is the rear door. This is of a usual form. In Fig. 4 it is shown suspended on two rollerhangers, F F, running on a suitable track, G.

All the foregoing may be of any ordinary construction of single-ended car.

I will now describe the novel way of mov ing the rear door from the front platform.

II a lever, fulcrumed at I to the car-body. The other end has a roller or other suitable device, J, running in a vertical way, K, at the edge of the door.

It will be seen that as the lever II is moved upward and downward on its fulcrum I that the door will be opened and closed. The lever is thrown up and down by the movement of the lever L, that extends from end to end of the ear beneath the seat and between the wheel-hoods and the side. This lever is fulcrumed on a post, M, so that its rear end can be moved upward and downward a sul'licient (No model.)

distance to cause the door to open and close.

The rear end of the lever L is connected to the central part of the lever II by a rod, N, the connection being direct, so that the rear end of the lever L and the free end of the lever II move upward and downward together, the latter moving a greater distance. The front end, Z, of the lever L projects through a vertical slot, 0, in the front wall of the car, and enters a slot, p, in a treadle-lever, I, that is fulcrumed to the front of the car at Q, and which has a closed stirrup, It, to receive the toe of the driver, so that by a simple movement of the foot he can raise or depress the fore end of thelever L, and thus open or close the door E.

In the modification shown in Fig. 5 the middle of the lever II is connected by a rod, S, to the side of the door-by joints 8 s. In this case it will be seen that the hanger at that side of the door may be dispensed with, because the joint s will necessarily remain at the same altitude in all positions of the door. Thus the lever Hand rod S will sustain that side'of the door if the other side is sustained, so as to keep the way K vertical.

It is obvious that the parts might be reversed by fulcruming the lever II to the door, and by making the way K for the other end upon the carbody. In this case the rod S would be connected to the body of thecar and to the lever H.

I have shown my preferred manner of connecting the end of the lever L with the door so as to cause the moving of the latter by the lever L; but I do not confine myself to the means set forth. The essential features of my invention are the lever L, extending from end to end of the car, with one end connected to the door in such a manner as to cause the opening and closing of the door by the movement of the lever. In the diagram Fig. (3, I show one of the many devices that may be used for such connection, the rod Nbeing connected to the ends of toggle-arms II S, connected to the door E and car A.

I claim as my invention- 1'. The combination, with the ear-door, of a lever, II, fnlcrumed to the side of the car at one end and sliding in a vertical way of the door at the other end, or vice versa, the connecting rod rlink N, adapted to be raised and lowered, and lever L, extending to the other end of the car and adapted to rock in a vertical plane. 5

2. The combination of lever L, rod N, lever H, and car and car-door with the rod S, con necting the parts, substantially as and for the purpose Set forth. 3. The combination, in a street-ear, of the treadle-lever 1?, side lever, L, rod N, lever H, rod S, and car-door with single roller-hanger F, all arranged substantially as shown and described.

4. The combination of a single lever, L, within the car above the floor, extending from end to end of the car-body and pivoted to rock in a vertical plane, a car-door, a lever connected to the side of the car and to the door, and a rod hinged to the lever L and to the lever above, and moved vertically to raise .and lower the lever above to open and close the door, as set forth.

The combination of a door, E, connec- FREDERIQK B. BROW'NELL.
